2250 Hydrostatic Level Sensor

The Signet 2250 Hydrostatic Level Sensor for level and depth control has a one-piece injection-molded PVDF body and ceramic diaphragm for superior compatibility in corrosive liquids. Utilizing hydrostatic pressure, the 2250 Level Sensor disregards false level signals from steam vapors, foam or any other debris on the liquid surface. Two pressure ranges allow for optimal resolution matched to your sensing needs. Solid state circuitry eliminates drift (no internal potentiometers).

These sensors are available with a proprietary digital output (S^3L), or 4 to 20 mA output. The extended cable and capillary tubing with the union connection and a customer-supplied conduit, allow submersion in process vessels.

Fields of Application:
  • Inventory Management
  • Storage Tank Monitoring
  • Neutralization Tanks
  • Plating Lines
  • Waste Sumps
  • Clarifiers
  • Overflow Protection
Standards:
  • CE
  • FCC
  • RoHS compliant
  • China RoHS
Advantages:
  • Level/depth measurement
  • 4 to 20 mA or digital (S3L) output
  • Flush ceramic diaphragm
  • Easy submersible installation
  • Choice of two pressure ranges
  • Standard union connection and extended cable and capillary tubing 10 m (32.8 ft)
